All About Ice
Why Study Ice on Mars?
On Earth, there’s a plethora of variables driving environmental change, from natural processes to the activities of humans. While Mars is most similar to Earth of all the known extraterrestrial worlds, its climate is still extremely different from our watery abode. The recent discovery of ice on the red planet’s surface has given us a new climate driver to study....

Meteor Crater is a 180 m deep, 1.2 km diameter bowl-shaped impact crater in Northern Arizona, and has long been a terrestrial analog site for planetary exploration. During the 1960’s, Eugene Shoemaker trained NASA astronauts at the crater to prepare for the Apollo missions to the Moon. The Meteor Crater Sample Collection consists of geologic samples from the Meteor Crater ejecta blanket.
The goals for this website are to catalog completed geologic maps and to help track the progress of currently funded maps. If you would like to propose for a mapping investigation, check the appropriate planetary body in the map index or refer to the various mapping pages (linked under Maps above) to see which geologic maps may have already been published or are currently in progress.
Rapid estimation of recharge potential in ephemeral-stream channels using electromagnetic methods, and measurements of channel and vegetation characteristics
To classify recharge potential (RCP) in ephemeral-stream channels, a method was developed that incorporates information about channel geometry, vegetation characteristics, and bed-sediment apparent electrical conductivity (??a). Recharge potential is not independently measurable, but is instead formulated as a site-specific, qualitative parameter...

Image of the Week - London Bridge in Arizona
London Bridge was indeed falling down. Set to be torn apart and replaced in the 1960s, this bridge across the River Thames was purchased by businessman Robert McCulloch in April 1968 and shipped across the Atlantic, to Lake Havasu City, Arizona, billed as the world's largest antique. USGS aerial photos show the location in 1969, and in 1972, before and after the bridge's
